1. Field of the Invention
The present invention relates generally to telescope mounts, and more particularly, to a disc-based alt-azimuth mount for telescopes.
2. Description of the Prior Art
A wide variety of telescope mounts are available for both astronomical and non-astronomical telescopes. These generally fall under two broad categories, namely equatorial and altitude-azimuth mounts. Equatorial mounts are designed to follow the celestial sphere by moving the telescope in one axis only. An alt-azimuth mount, on the other hand, is designed to move in two axes to follow both the celestial sphere and the vertical altitude dimension.
Because of its simplicity, the alt-azimuth mount has gained popularity in recent years as a multi-purpose astronomical and non-astronomical mount. The new professional telescopes are now being built with alt-azimuth mounts and computer driven motors moving in both axes to track celestial objects. The mount has also gained popularity with the advent of new precision-built and optically-correct wide field refractor (lens in front) telescopes being used for astronomical and terrestrial objects.
Unfortunately, existing alt-azimuth telescope mounts have proven to be quite amendable to vibrations and do not remain rigid to outside forces such as wind or touch. Such vibrations are most evident in single arm mounts and intensify as the length of the arms is increased. Although adding a second arm has reduced this problem somewhat, it has lead to a host of other design deficiencies, such as not being able to carry telescopes of varying widths. One notable drawback found in existing alt-azimuth telescope mounts is that they are not able to handle telescopes of varying sizes without the addition of counter-balance devices and do not permit the mount to swing freely without interference from the telescope hitting the base of the mount.
A further problem encountered with existing alt-azimuth telescope mounts is that they are not able to handle various size loads such as cameras, eyepieces and the like without unwanted movement caused by imbalance. Many telescopes allow the observer to interchange eyepieces, allowing an increase or decrease in magnification. Cameras may also be used in place of eyepieces in order to take pictures. Modern eyepieces weight can range from as little as two ounces for high magnification, to over two and a half pounds for a wide field low magnification. If the telescope is balanced for a heavy eyepiece and the eyepiece is removed, the telescope will rotate forward. Likewise, if the telescope is balanced for a light weight (or no eyepiece), then the telescope will drop in the rear. To overcome this problem, some mounts have locks to prevent the axis from moving. The observer moves the telescope to the object and locks the axis. However, the object seldom remains stationary (a sighted dear runs or the earth rotates, for example). In order to address this problem, designers have added slow motion mechanisms. These mechanisms, however, have generally proven cumbersome and inadequate in practice because the mount axis must be locked during use. Similarly, friction locks have not adequately addressed this issue.
Additionally, existing mounts often do not maintain all axes and planes perfectly orthogonal with each other as required for accuracy when electronic shaft encoders are utilized with computerized locaters, commonly known in the art as setting circles. Significant errors are introduced where the axes of the telescope mount are not perfectly orthogonal.
Accordingly, there is an established need for a disc based alt-azimuth telescope mount for use with any of a variety of existing telescopes that addresses and overcomes the aforementioned problems and disadvantages found in existing telescope mounting systems.
The present invention is directed to a disc based alt-azimuth telescope mount for use with any of a variety of existing telescopes.
An object of the present invention is to provide a disc based alt-azimuth telescope mount that permits the magnitude of friction to be easily adjusted between discs.
A further object of the present invention is to provide a disc based alt-azimuth telescope mount wherein ball bearings rather than the disc surface are utilized to permit a disc-tightening nut to turn with the shaft of the telescope mount.
It is also an object of the present invention to provide a disc-based alt-aximuth telescope mount that does not require constant friction adjustment.
Another object of the present invention is to provide a disc based alt-azimuth telescope mount that eliminates the need to utilize set screws, pins, and other mechanisms that permit friction adjusting nut loosening over time.
An additional object of the present invention is to provide a disc based alt-azimuth telescope mount that is configured to accept any of a wide variety of loads such as eyepieces, cameras, and the like, without rebalance.
Yet another object of the present invention is to provide a disc based alt-azimuth telescope mount wherein the axes are orthogonal such that the shafts within each axis are positioned at right angles.
A further object of the present invention is to provide a disc based alt-azimuth telescope mount configured to permit electronic shaft encoders to be mounted directly to the axis shafts.
Another object of the present invention is to provide a disc based alt-azimuth telescope mount optionally fitted with electronic shaft encoders which, when used, are located on the same plane of the corresponding azimuth or altitude axis so that battery-powered astronomical setting circles and other equipment can be utilized without cables interfering with the telescope mount operation.
An additional object of the present invention is to provide a disc based alt-azimuth telescope mount that is compact in size and easy to store and transport.
Yet another object of the present invention is to provide a disc based alt-azimuth telescope mount wherein the telescope is mounted to the side and hangs over the side of the mount such that it is capable of aiming through a wide range from below the horizon to overhead.
A further object of the present invention is to provide a disc based alt-azimuth telescope mount wherein rigidity due to the close coupling (short arms) is inherent to the design.
Another object of the present invention is to provide a disc based alt-azimuth telescope mount designed for use with both astronomical and terrestrial telescopes and lenses.
An additional object of the present invention is to provide a disc based alt-azimuth telescope mount that does not require locks during the use of slow motion controls.
These and other objects, features, and advantages of the present invention will become more readily apparent from the attached drawings and the detailed description of the preferred embodiments, which follow.
The preferred embodiments of the invention will hereinafter be described in conjunction with the appended drawings provided to illustrate and not to limit the invention, where like designations denote like elements, and in which:
Shown throughout the figures, the present invention is generally directed towards a disc based alt-azimuth telescope mount for use with any of a variety of existing telescopes.
Referring initially to
A prior art altitude-azimuth (also called alt-azimuth or azimuth) telescope mount 78 is shown in
Referring to
Briefly, and as hereinafter further described, the telescope mount 1 includes an azimuth disc assembly 8, which is mounted on the tripod 2; a mount housing 23, which is mounted on the azimuth disc assembly 8; and an altitude disc assembly 13, which is mounted on the mount housing 23. As illustrated in
As shown in
As illustrated in
A side support plate 25 typically slidably and removably engages the front support plate 24 and the rear support plate 27, as illustrated in
As further illustrated in

Referring next to
As illustrated in
As further illustrated in
It will be appreciated by those skilled in the art that the azimuth disc assembly 8 and the altitude disc assembly 13 must be frictionally adjusted so as to prevent inadvertent drifting or movement of the telescope 37 from a sighted position during use. This adjustment is typically only required during the initial setting up of a new telescope on the mount or substantial changes in auxiliary equipment, such as, for example, during changing of a heavy eyepiece for a lighter eyepiece. This is accomplished by using a tool, such as a wrench (not shown), to tighten the friction adjusting nuts 17 against the adjusting nut bearings 16 of the respective azimuth disc assembly 8 and altitude disc assembly 13. Accordingly, as best illustrated in
After a period of time has elapsed since initial sighting of the celestial object through the telescope 37, it frequently becomes necessary to re-adjust the position of the telescope 37 along the azimuth axis 40 to compensate for the rotation of the earth. Accordingly, it is seen that the telescope can be manually moved by the observer by overcoming the friction between the disc 19 and the friction disc spacer 21 by applying sufficient force to permit the telescope 37 to move freely. Upon coming to rest, however, the friction between the disc 19 and the friction disc spacer 21 will preferably be sufficient to maintain the current position in a secure manner until movement to a new position is desired.
In the present invention, the disc based alt-azimuth telescope mount 1 is configured with the altitude axis disc assembly 13 mounted to the side of the azimuth axis disc assembly 9. The telescope 37 can be mounted in the center of gravity of the altitude axis 41. As such, no counter balance will be required and the telescope 37 will not hit the azimuth axis 40. Because no counter balance is needed, the shafts 14 can be kept short and smaller in diameter. This will allow the shafts 14 to terminate on the same plane. The electronic shaft encoders 30 may be mounted directly to the ends of the shafts 14. This is a major advantage because battery-powered digital setting circles 28 may be mounted without external cables 29 passing through the shafts 14 or wrapping around the mount 1 as it is turned on its axis.
In a most preferred embodiment, the disc based telescope mount will include a shaft threaded on one end such that a nut can be used to allow the disc to be pulled together. This permits the tension or friction between the disc to be easily adjustable. In the disc based telescope mount of the present invention, a ball bearing assembly will be added between the nut and the disc. This permits the nut to turn freely with the shaft and still be easily adjustable.
As shown in
Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
